Read "To the Beloved" at The Eldritch Dark:
This sonnet presents one of the most powerful declarations of love I've read in the English language, and allows Clark Ashton Smith (CAS) to speak in a voice that is atypical of his work. After describing various cosmic phenomena and comparing them to precious stones, he gets to the heart of the matter:
Hath held the troublous marvel and surprise
That gleams and trembles in thy slightest nod,
Or sleeps between thine eyelids and thine eyes.
Although the narrator has encountered amazing things on his journey "Through alien lives ineffable" he is ultimately most fascinated by seemingly mundane physical aspects of his beloved. It doesn't get much more romantic than that!
